Abstract

The invention relates to the liquid transmission and movement control technology, and in particular relates to an energy feedback type magneto-rheological-air floating combined performing device which is independent, adjustable in rigidity, controllable in damping and compact in structure. The device comprises a magneto-rheological damper for generating magneto-rheological effect to produce controllable damping, an energy feedback assembly for generating electricity energy during movement and feeding back to a driving power supply of the device, a sliding guide rail assembly for enabling relative sliding of the magneto-rheological damper and the energy feedback assembly, a friction-free cylinder for generating air floating effect, and a medium connecting assembly for integrally coupling all parts. According to the device, the air floating effect, air / a linear bearing are utilized to achieve friction-free performance and adjustable rigidity, and the output force and the response capacity of the performing device can be improved; the magneto-rheological effect enables quick response and adjustable damping, so that the stability and interference resistance of the positioning movement can be improved; the energy consumption can be reduced through energy feedback, and thus the energy saving efficiency of the system can be increased. The device is applied to the condition requiring compact structure, high speed, high precision and quick response.

Description

technical field [0001] The invention relates to the technical field of fluid transmission and motion control, in particular to an energy feedback magneto-rheological-air bearing composite actuator with independently adjustable stiffness and controllable damping and compact structure. The actuator can not only be used in precision motion occasions with large stroke, high precision and fast response in the fields of machinery, aerospace, vehicles, etc., but also can be used for intelligent vibration isolation and shock absorption under variable working conditions and disturbances in these fields. Background technique [0002] Pneumatic transmission has the characteristics of simple structure, convenient maintenance, safe operation, flexible and adjustable system stiffness and load counterweight, etc. Therefore, the cylinder actuator has certain dynamic and precision requirements, moderate load, and low cost (ten thousand yuan level) It has good applicability in precision motio...
